Abstract
Since the fabrication of active electrodes has been reported and their beneficial effects scientifically confirmed, we present a CMOS bioelectric amplifier with DC rejection designed for active electrode in this paper. Analysis, design and post simulation results will be described in detail. The amplifier operating at ±0.9V supply voltage has a mid-band gain of 40dB with ±300mV dc offset rejection and has a power consumption of 6.7μW. The bandwidth extends from a low-frequency cutoff of 7.9mHz to a high-frequency cutoff of 2.1kHz which is suitable for ECG signals. This proposed amplifier has an input-referred noise of 5.9μVrms. This amplifier is under fabrication in 0.18μm 1P6M CMOS Process.
